Technical barrier in engineering, obtains good Social and economic benef@, thus the technology is flourished.
In recent decades, different types of muscle material (from high molecular polymer of the metal of low ductility to high ductility) is used for
In earth structure, and high molecular polymer muscle material applies then wider in Reinforced Material with Clay Engineering.It is generally believed that less to rigidity
With direct shear friction test, geosynthetics, determines that its intensive parameter relatively meets reality；The material larger to rigidity, then using drawing
Pull out test preferably.American scholar McGown is proposed, for various earth structures, play reinforced action is all geotechnological synthesis
The resistance to plucking resistance of material, he determines boundary strength with pull-out test at opinion, while obtaining the stress-strain for being embedded in muscle material in soil
Relation.French Schdsser thinks that the advantage of pull-out test is that test result can reflect that the soil body cuts swollen and densification state automatically,
And preferably simulate working condition of the muscle material in soil.Field actual measurement results are it was demonstrated that pull-out test can simulate reinforced earth knot really

The factor of pull-out test result is affected to have a lot, be to be produced by pilot system below at 2 points：One is geotechnological synthesis
Rubbing action between material and box (case) wall, it increases applied pulling capacity, virtually enhances geosynthetics
Drawing characteristic；Two is drawing speed, the unstable estimation that will also result in geosynthetics drawing characteristic of drawing speed
Deviation.The purpose of test is the interface mechanical characteristic between studying geosynthetics and banketing, it is necessary in accurate recording test
The horizontal displacement of the normal pressure, pulling capacity and the geosynthetics that are applied.Therefore, the precision of pilot system is most important.
Simultaneously, it is also desirable to consider geosynthetics and receive the performance under different directions load whether different, should during design
Take the minima in all directions.
In sum, the geosynthetics that obtains of test and the interface mechanical characteristic between banketing often are better than engineering
There is larger hidden danger, seriously threaten engineering in geosynthetics and the interface mechanical characteristic for banketing in practice, its security performance
Quality and people life property safety.
